Objective To investigate the effect of varying ureteral wall thickness(UWT)at the site of ureteral stones on the clinical efficacy of ureteroscopic lithotripsy(URL).Methods The clinical data of 164 patients with ureteral stones in our hospital were retrospectively analyzed.According to different UWT,the patients were divided into the mild thickening group(84 cases,UWT<3.16 mm),the moderate thickening group(31 cases,UWT 3.16 to 3.49 mm),and the severe thickening group(49 cases,UWT>3.49 mm),and the differences of clinical related indicators among the three groups were compared.Results The incidence of postoperative renal colic and leukocyte disorder in the mild thickening group and the moderate thickening group were lower than those in the severe thickening group,and the differences were statistically significant(P<0.05).The postoperative catheterization time in the mild thickening group and the moderate thickening group were shorter than that in the severe thickening group,and the incidences of secondary lithotripsy,residual stones and stone return to kidney in the mild thickening group and the moderate thickening group were lower than those in the severe thickening group,with statistically significant differences(P<0.05).The length of hospital stay and hospitalization cost in the mild thickening group and the moderate thickening group were shorter/less than those in the severe thickening group,with statistically significant differences(P<0.05).Conclusion With the increase of UWT(especially when UWT>3.49 mm),the incidence of postoperative complications and hospitalization cost of URL increase to varying degrees,and the surgical efficacy decreases.In clinical work,UWT measurement holds potential value in predicting the surgical efficacy and complications of URL.

Traumatic supraorbital fissure syndrome (TSOFS) is a symptom complex caused by nerve entrapment in the supraorbital fissure after skull base trauma. If the compressed cranial nerve in the supraorbital fissure is not decompressed surgically, ptosis, diplopia and eye movement disorder may exist for a long time and seriously affect the patients′ quality of life. Since its overall incidence is not high, it is not familiarized with the majority of neurosurgeons and some TSOFS may be complicated with skull base vascular injury. If the supraorbital fissure surgery is performed without treatment of vascular injury, it may cause massive hemorrhage, and disability and even life-threatening in severe cases. At present, there is no consensus or guideline on the diagnosis and treatment of TSOFS that can be referred to both domestically and internationally. To improve the understanding of TSOFS among clinical physicians and establish standardized diagnosis and treatment plans, the Skull Base Trauma Group of the Neurorepair Professional Committee of the Chinese Medical Doctor Association, Neurotrauma Group of the Neurosurgery Branch of the Chinese Medical Association, Neurotrauma Group of the Traumatology Branch of the Chinese Medical Association, and Editorial Committee of Chinese Journal of Trauma organized relevant experts to formulate Chinese expert consensus on the diagnosis and treatment of traumatic supraorbital fissure syndrome ( version 2024) based on evidence of evidence-based medicine and clinical experience of diagnosis and treatment. This consensus puts forward 12 recommendations on the diagnosis, classification, treatment, efficacy evaluation and follow-up of TSOFS, aiming to provide references for neurosurgeons from hospitals of all levels to standardize the diagnosis and treatment of TSOFS.

Lung is the largest organ of the respiratory system. During hypoxia, pulmonary cells undergo rapid damage changes and activate the self-rescue pathways, thus leading to complex biomacromolecule modification. Death from mechanical asphyxia refers to death due to acute respiratory disorder caused by mechanical violence. Because of the absence of characteristic signs in corpse, the accurate identification of mechanical asphyxia has always been the difficulty in forensic pathology. This paper reviews the biomacromolecule changes under the pulmonary hypoxia condition and discusses the possibility of application of these changes to accurate identification of death from mechanical asphyxia, aiming to provide new ideas for related research.

Objective:To evaluate the efficacy and safety of adalimumab (ADA) in the treatment of Crohn′s disease (CD), and to analyze the predictive factors of ADA efficacy.Methods:From January 2020 to December 2020, 49 CD patients treated with ADA at the Department of Gastroenterology, Tenth People′s Hospital of Tongji University of Shanghai were enrolled. The clinical data before treatment were collected. During 12 weeks of ADA treatment, the patients were followed up every 2 weeks, the laboratory examinations were conducted every 4 weeks, and colonoscopy examination was rechecked at the 12th week. The improvement of the main symptoms of patients was assessed at 2nd, 4th, and 6th week during ADA treatment. At the 12th week after ADA treatment, the clinical response (Crohn′s disease activity index (CDAI) score decreased ≥70 points from baseline), clinical remission (CDAI score < 150 points), endoscopic response (simple endoscopic score for Crohn′s disease (SES-CD) decreased >50% from baseline) and endoscopic remission (SES-CD ≤2 points or Rutgeerts score ≤1 point), closure of anal fistula of CD patients complicated with anal fistula and occurrence of adverse reactions during treatment were recorded. The predictive factors of clinical remission of CD patients after ADA treatment for 12 weeks were analyzed. The Mann-Whitney U test and binary logistic regression analysis were used for statistical analysis. Results:The main symptom improved rates of 49 CD patients received ADA treatment at 2nd, 4th and 6th week were 75.5% (37/49), 95.9% (47/49) and 98.0% (48/49), respectively, and the main symptom improved time was 14.0 d (7.0 d, 17.0 d). After ADA treatment for 12 weeks, the clinical remission rate was 55.1% (27/49), the clinical response rate was 73.5% (36/49), the endoscopic remission rate was 43.3% (13/30), the endoscopic response rate was 55.6% (15/27), the anal fistula closure rate was 7/18, and the overall incidence of adverse reactions was 24.5% (12/49). The baseline of fecal calprotectin (FC) level of patients in the clinical remission group (27 cases) was lower than that of the patients in the active disease group (22 cases) (111.0 μg/g, 26.3 μg/g to 125.6 μg/g vs. 540.5 μg/g, 420.2 μg/g to 866.9 μg/g), and the difference was statistically significant ( Z=-4.44, P<0.001). The results of binary logistic regression analysis showed that baseline FC level was an independent predictive factor of clinical remission in CD patients treated with ADA for 12 weeks ( OR=1.08, 95%confidence interval 1.02 to 1.14, P=0.013). When the baseline FC cut-off value was 172.39 g/g, the sensitivity and specificity of it in predicting clinical remission in CD patients treated with ADA for 12 weeks were 81.48% and 90.91%, and the area under the receiver operator characteristic curve was 0.87 ( P<0.001). Conclusions:ADA is safe and effective in the treatment of CD. The baseline FC level is an independent predictive factor of clinical remission in CD patients treated with ADA for 12 weeks.

Objective:To explore any correlation between knee muscle strength and walking ability after an incomplete lumbar spinal cord injury and the factors influencing walking ability.Methods:Twenty-seven persons with an incomplete lumbar spinal cord injury were tested. Their bilateral quadriceps and hamstring muscle strength and peak torque during knee extension and flexion were assessed. They completed the 10m walking time test (10MWT) and each person′s WWISCI II spinal cord injury walking index was evaluated. Spearman correlations among the data were computed and stepwise regression was used to analyze the factors significantly influencing the 10MWT and WISCI II results.Results:The average hamstring strength was significantly negatively correlated with the 10MWT times and WISCI II ratings. Hamstring torque also was negatively correlated with the 10MWT times, but positively correlated with the WISCI II ratings. The 10MWT times and WISCI II ratings were significantly inter-correlated. Hamstring strength was the best predictor of 10MWT times (accounting for 63% of the variance) and WISCI II ratings (64%), but quadriceps strength was also a secondary predictor.Conclusions:Knee muscle strength is a useful predictor of 10MWT times and WISCI II ratings after incomplete lumbar spinal cord injury. It can predict early walking ability to some extent.

Gastric schwannoma is a tumor originating from mesenchymal tissue. The clinical incidence is relatively rare, accounting for 6.3% of all gastric stromal tumors. The tumor is more likely to occur in the body of the stomach and usually originates from the gastric submucosal nerve. Most gastric schwannomas do not have any clinical symptoms. Imaging examination can play a diagnostic role, but the diagnosis still requires pathological examination, especially S-100 protein which is the gold standard for the diagnosis of gastric schwannomas. Gastric schwannoma usually needs to be distinguished from gastrointestinal stromal tumors and gastrointestinal autonomic nerve tumors. In terms of treatment, complete surgical resection is the first choice.

On the basis of systematic evaluation of 32 provincial capital cities and municipalities in their capacity for preventing and controlling emerging infectious diseases, focus analysis is made on Wuhan in relation to its advantages and disadvantages as follows:There has been a legal basis for epidemic prevention according to law, but it has not translated into effective action.There has been an organizational basis for responding to epidemic, but coordination mechanism has not been effectively established.The management mechanism has been complete, but the division of responsibilities among different departments has not been clear.The monitoring network has been set up, but its role of "predictive warning" has not been played.Insufficiency of public health service delivery was observed owing to lack of financial investment.In cities of China, advantages and disadvantages have been both existent in their capacity to prevent and control of emerging infectious disease.We should be vigilant in this regard. It is imperative to "fill defects, stop leaks and strengthen weakness".There is a Chinese saying:"It is not too late to mend a fold after the sheep have been stolen".

Systematic evaluation of the effectiveness and safety of Xiaoer Xiaoji Zhike Oral Liqud combined with azithromycin in the treatment of mycoplasma pneumonia in children. Clinical literatures were retrieved from PubMed, Cochrane Library, EMbase, VIP, CNKI, SinoMed, WanFang from inception to September 2019. Two reviewers independently screened out the literatures, extracted data and assessed the risk of bias of the included studies. Then, Meta-analysis was performed by RevMan 5.3 software. A total of 17 RCT were included, involving 1 712 patients. In this study, there were two subgroups by the application approach of azithromycin: oral azithromycin subgroup and intravenous azithromycin subgroup. According to Meta-analysis results, in terms of the alleviation of clinical symptoms and signs, such as shortening of antifebrile time, cough disappeared time, rales disappearance time, and lung X-ray infiltrating shadow disappearance time, Xiaoer Xiaoji Zhike Oral Liquid combined with oral azithromycin or intravenous azithromycin were better than single-dose azithromycin; in the aspect of the improvement of the overall effective rate, the two combination subgroups were better than the single-use azithromycin; In terms of the decline of IgM, the combination subgroups were also more efficient than the single-use azithromycin, with statistically significant differences. In terms of the incidence of adverse reactions, there was no significant difference between the two combination subgroups and the single-use azithromycin in children, and no serious adverse reactions were found. In inclusion, Xiaoer Xiaoji Zhike Oral Liquid combined with azithromycin can improve the clinical efficacy in treating pediatric mycoplasma pneumonia, with a high safety. Due to the limited quantity and quality of the included studies, more high-quality studies are needed to verify the above conclusion.
